Interactions with sulfur acceptors modulate the reactivity of cysteine desulfurases and define their physiological functions.

Sulfur-containing biomolecules such as [FeS] clusters, thiamin, biotin, molybdenum cofactor, and sulfur-containing tRNA nucleosides are essential for various biochemical reactions. The amino acid l-cysteine serves as the major sulfur source for the biosynthetic pathways of these sulfur-containing cofactors in prokaryotic and eukaryotic systems. The first reaction in the sulfur mobilization involves a class of pyridoxal-5'-phosphate (PLP) dependent enzymes catalyzing a Cys:sulfur acceptor sulfurtransferase reaction.

Is vitamin D receptor (VDR) polymorphism associated with head and neck cancer risk? A systematic review and meta-analysis.

Background: Head and neck cancer encompasses neoplasms affecting the oral cavity, pharynx, larynx, and thyroid. Identifying factors that modulate the carcinogenesis process can aid in identifying subgroups at higher risk of developing the disease, enabling implementation of prevention programs. Vitamin D receptor polymorphisms can affect the carcinogenesis of various tumors by altering vitamin D metabolism and cellular response.

Use of Nile tilapia (Oreocromis niloticus) processing residues in the production of pâtés with the addition of oregano (Origanum vulgare) essential oil.

The effect of the use of Nilo tilapia filleting residues in the production of pâtés with the addition of oregano essential oil stored for 90 days at 4 °C was evaluated. For that, 5 treatments were performed as follows: TSA-control treatment; TES with the addition of sodium erythorbate; and formulation TOE1 with 600 ppm oregano essential oil; TOE2 with 1000 ppm essential oil; and TOE3 with 1400 ppm essential oil. The pâtés showed adequate technological and physicochemical characteristics and microbiological counts within the legislation standards.

Sulfinamide Formation from the Reaction of Bacillithiol and Nitroxyl.

Bacillithiol (BSH) replaces glutathione (GSH) as the most prominent low-molecular-weight thiol in many low G + C gram-positive bacteria. BSH plays roles in metal binding, protein/enzyme regulation, detoxification, redox buffering, and bacterial virulence. Given the small amounts of BSH isolated from natural sources and relatively lengthy chemical syntheses, the reactions of BSH with pertinent reactive oxygen, nitrogen, and sulfur species remain largely unexplored.

The alpha-synuclein oligomers activate nuclear factor of activated T-cell (NFAT) modulating synaptic homeostasis and apoptosis.

Background: Soluble oligomeric forms of alpha-synuclein (aSyn-O) are believed to be one of the main toxic species in Parkinson's disease (PD) leading to degeneration. aSyn-O can induce Ca influx, over activating downstream pathways leading to PD phenotype. Calcineurin (CN), a phosphatase regulated by Ca levels, activates NFAT transcription factors that are involved in the regulation of neuronal plasticity, growth, and survival.

Interaction of Hoechst 33342 with POPC Membranes at Different pH Values.

Hoechst 33342 (H33342) is a fluorescent probe that is commonly used to stain the DNA of living cells. To do so, it needs to interact with and permeate through cell membranes, despite its high overall charge at physiological pH values. In this work, we address the effect of pH in the association of H33342 with lipid bilayers using a combined experimental and computational approach.

Sustainability approaches for agrowaste solution: Biodegradable packaging and microbial polysaccharides bio-production.

Global growth impacts on the increased use and demand for natural resources, requiring solutions for the high volume of industrial waste and by-products generated from the most diverse commercial areas, mainly the food sector. Among the main residues with a large volume generated, those from fruit processing, grain cleaning in processing units, vegetables, and discards from the animal production industry stood out.

The effect of volunteer-led activities on the quality of life of volunteers, residents, and employees of a long-term care institution: a cohort study.

Background: The COVID-19 pandemic primarily impacted long-term care facilities by restricting visiting and circulation of visitors, affecting the quality of life (QoL) of older adults living in these institutions. Volunteer activities, essential for older adults' daily life, were also interrupted and potentially negatively impacted the QoL of older adults, volunteers themselves, and also employees in these institutions. In this context, this study aims to evaluate the impact of the return of volunteer-led activities in a long-term care institution on the QoL of older adult residents, employees, and volunteers.

Overview of physiological, biochemical, and regulatory aspects of nitrogen fixation in .

Understanding how Nature accomplishes the reduction of inert nitrogen gas to form metabolically tractable ammonia at ambient temperature and pressure has challenged scientists for more than a century. Such an understanding is a key aspect toward accomplishing the transfer of the genetic determinants of biological nitrogen fixation to crop plants as well as for the development of improved synthetic catalysts based on the biological mechanism. Over the past 30 years, the free-living nitrogen-fixing bacterium emerged as a preferred model organism for mechanistic, structural, genetic, and physiological studies aimed at understanding biological nitrogen fixation.

Inter- and intra-island speciation and their morphological and ecological correlates in Aeonium (Crassulaceae), a species-rich Macaronesian radiation.

Background And Aims: The most species-rich and ecologically diverse plant radiation on the Canary Islands is the Aeonium alliance (Crassulaceae). In island radiations like this, speciation can take place either within islands or following dispersal between islands. Aiming at quantifying intra- and inter-island speciation events in the evolution of Aeonium, and exploring their consequences, we hypothesized that (1) intra-island diversification resulted in stronger ecological divergence of sister lineages, and that (2) taxa on islands with a longer history of habitation by Aeonium show stronger ecological differentiation and produce fewer natural hybrids.

Plant growth forms dictate adaptations to the local climate.

Adaptive radiation is a significant driver of biodiversity. Primarily studied in animal systems, mechanisms that trigger adaptive radiations remain poorly understood in plants. A frequently claimed indicator of adaptive radiation in plants is growth form diversity when tied to the occupation of different habitats.

Absence of N-Acetylglucosamine Glycosylation on Wall Teichoic Acids Promotes Fatty Acid Tolerance by Repulsion From the Bacterial Surface.

Free fatty acids (FFAs) have strong antimicrobial properties against pathogenic bacteria and are known as natural protective agents against bacterial infections. Growth of the foodborne pathogen is highly affected by the presence of antimicrobial FFAs, however, the response of toward FFAs is not fully understood. Here, we explore how gains tolerance toward FFAs and present a novel mechanism conferring bacterial protection against FFA toxicity.

The Global Regulator CcpA of Confers Sensitivity to Antimicrobial Fatty Acids.

Free fatty acids (FFAs) are known to exhibit antimicrobial and anti-virulent properties against bacterial pathogens. Specific FFAs, such as lauric acid (LA; C12:0), exert both effects against the foodborne pathogen : at low levels, LA acts to inhibit the activity of the virulence regulator PrfA, whereas at higher levels, LA inhibits bacterial growth. Deletion of is known to promote tolerance toward antimicrobial FFAs, suggesting that the response of to anti-virulent and antimicrobial FFAs could be linked.
